Netptune has 8 named moons (4 unnamed) and has large storms with the fastest winds of any planet in the solar system (2000 km/hr.).
The unit of frequency is the hertz (Hz), one cycle per second, named after Heinrich Hertz. For our purposes, we shall use much higher frequencies. One thousand Hz is a kHz (kilohertz); one thousand kHz is a MHz (megahertz); one thousand MHz is a GHz (gigahertz); one thousand GHz is a THz (terahertz).
Named after Heinrich Hertz and abbreviated as Hz or illustrated as the f symbol, hertz equals one (0.00000000125) cycle per second, measuring the waves or frequencies of electric changes each second. Hertz is commonly used to measure a computer monitor's refresh rate and in computer processors.
